Technical Field
[0001] This utility model relates to the field of flute manufacturing technology, and in particular to a flute marking device. Background Technology
[0002] During flute manufacturing, the positions of all holes on the flute tube need to be determined. The positions of the holes differ for flutes of different keys, and the length of the flute tube also varies during manufacturing. Therefore, the positions of the holes must be determined before drilling them. Currently, a marking board is typically used to mark these holes. The marking board consists of two boards spaced a certain distance apart, with multiple lines connected between them. The ends of these lines are attached to the two boards. Among these lines are fundamental tone lines, tuning lines, and finger hole lines. The positions of these lines differ for flutes of different keys. Therefore, the positions of each line must be adjusted and fixed before marking can begin. This process is cumbersome, inefficient, and the accuracy of the markings is relatively low. Therefore, a dedicated flute marking device needs to be designed. Summary of the Invention
[0003] The purpose of this invention is to solve the problems of cumbersome operation, low efficiency, and low accuracy of drawing lines on a flute in the prior art, and to provide a flute line drawing device.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A flute marking device includes a worktable, a flute support assembly, and an adjustable light source assembly. The adjustable light source assembly is located on one side of the worktable, and the flute support assembly is located on the other side. Multiple standard templates are provided between the adjustable light source assembly and the flute support assembly. Each standard template has standard hole positions corresponding to holes on a bamboo flute of different melodies. The adjustable light source assembly includes a rotating shaft mounting base, a rotating shaft, a base plate, a guide rail, sliders, and multiple light sources. There are two rotating shaft mounting bases, which are arranged opposite each other. The rotating shaft is connected between the two mounting bases. The base plate is rotatably connected to the rotating shaft. The guide rail is fixedly mounted on the base plate. Multiple sliders are slidably connected to the guide rail. The number of sliders corresponds to the number of light sources. Each slider has a fixed light source. By moving the slider, the light emitted by each light source can correspond to the standard hole positions on the standard templates. The flute support assembly is rotatably connected to the worktable.
[0006] In the above solution, the flute support assembly includes a V-groove support and a rotating shaft. The rotating shaft is located below the V-groove support, and the V-groove support is rotatably connected to the worktable via the rotating shaft. With this configuration, the V-groove support can support the bamboo flute, ensuring it is stably supported within the V-groove. By using the rotating shaft, the V-groove support can rotate horizontally relative to the worktable, adjusting the angle between the V-groove support and the light emitted from the adjustable light source assembly.
[0007] In the above scheme, a boss is provided on the worktable, and the adjustable light source assembly is mounted on the boss. By providing the boss, the height of the adjustable light source assembly can be higher than the height of the standard templates and V-groove supports on the worktable, so that the light emitted by the light source can illuminate the flutes placed on each standard template and V-groove support, which facilitates the adjustment of the slider of the adjustable light source assembly and the marking of the opening position of the flute.
[0008] In the above solution, the slider is equipped with a locking bolt, and the slider is fixedly connected to the guide rail by the locking bolt. By setting the locking bolt, after the slider is adjusted to the correct position, the locking bolt can be used to fix the slider on the guide rail, preventing the position of the light source from shifting.
[0009] In the above scheme, the standard template includes several of the following: A major, B major, C major, D major, E major, F major, G major, major A major, major B major, and major G major. Through this setting, this invention can draw lines on flutes in various keys, making its application range wider and its versatility better.
[0010] In the above scheme, the workbench is provided with a slot, and the standard template is plugged into the slot. This configuration allows the standard template to be replaced, facilitating the assembly of the corresponding standard template when drawing lines on flutes of different keys.
[0011] This invention has the following positive effects: 1) The flute marking device of this invention includes a flute support assembly and an adjustable light source assembly on the worktable. The flute support assembly rotates and cooperates with the worktable. Therefore, when marking lines, the flute support assembly can be rotated and adjusted so that the fundamental tone line and tuning line on the flute are aligned with the fundamental tone line and tuning line on the standard template corresponding to the key. This allows light corresponding to other standard hole positions to be projected onto the flute, thus marking the positions of the remaining holes on the flute. This method improves the positioning accuracy and efficiency of the holes on the flute. 2) This flute marking device can mark lines on flutes of various keys. When marking lines, it is only necessary to adjust the position of the light source according to the standard hole positions on the standard template of the key to be marked. The operation is simple and quick, and the adjustment accuracy is high, which can improve the sound effect of the supported flute. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the flute marking device of this utility model.
[0013] The attached figures are labeled as follows: worktable 1, boss 11, flute support assembly 2, V-groove support 21, rotating shaft 22, adjustable light source assembly 3, rotating shaft mounting base 31, rotating shaft 32, base plate 33, guide rail 34, slider 35, light source 36, locking bolt 37, standard template 4, standard hole position 41, flute tube 5. Detailed Implementation
[0014] The technical solution of this utility model will be clearly and completely described below through embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0015] like Figure 1 As shown, the flute marking device of this utility model includes a worktable 1, a flute support assembly 2, and an adjustable light source assembly 3.
[0016] Workbench 1 can be a workbench with a certain strength, such as a wooden workbench, a plastic workbench, or a metal workbench.
[0017] In order for the light source to illuminate each standard template 4, a boss 11 can be set on the workbench 1. The boss 11 is used to set the adjustable light source assembly 3.
[0018] Several standard templates 4 are provided in the middle of the workbench 1. The number of standard templates 4 can be set as needed. For example, it can include standard templates of all keys, such as several of A, B, C, D, E, F, G, major A, major B and major G.
[0019] Multiple standard templates 4 can be set in parallel at a certain interval, and each standard template 4 is provided with a standard hole position 41 corresponding to it.
[0020] The connection method between the standard template 4 and the worktable 1 can be selected as needed. For example, various standard templates 4 can be fixedly connected to the worktable 1. When drawing lines, the required standard template 4 can be directly selected. The advantage of this method is that the standard template 4 is fixedly connected to the worktable 1, which is not prone to displacement and can ensure its positional accuracy. Another implementation method is to set a slot on the worktable 1. After selecting the tune of the flute, select the corresponding standard template 4, and then insert the standard template 4 into the slot on the worktable 1. The advantage of this method is that it does not require setting multiple standard templates 4 on the worktable 1; the standard template 4 can be selected and then inserted for installation.
[0021] The adjustable light source assembly 3 is disposed on the worktable 1, preferably on the boss 11.
[0022] The adjustable light source assembly 3 includes a rotating shaft mounting base 31, a rotating shaft 32, a base plate 33, a guide rail 34, a slider 35, and multiple light sources 36.
[0023] There are two rotating shaft mounting seats 31, which are arranged opposite each other. A rotating shaft 32 is connected between the two rotating shaft mounting seats 31, and a seat plate 33 is rotatably connected to the rotating shaft 32. With this arrangement, the seat plate 33 can be adjusted vertically within a certain range. For example, when adjusting the position of the light source, the seat plate 33 can be adjusted vertically so that the light emitted by each light source can sequentially illuminate the standard holes on the corresponding standard template 4. After adjusting the position of the light source, the seat plate 33 can be adjusted upwards so that the light emitted by the light source illuminates the flute 5 on the flute support assembly 2.
[0024] The guide rail 34 is fixedly mounted on the base plate 33. The setting direction of the guide rail 34 is consistent with the setting direction of the standard template 4, so that the direction of the light emitted by the light source 36 can correspond to the standard template 4 and can illuminate the flute tube 5 that needs to be drawn.
[0025] Multiple sliders 35 are slidably connected to guide rails 34. Each slider 35 is equipped with a locking bolt 37, and the slider 35 is fixedly connected to the guide rail 34 by the locking bolt 37. The number of sliders 35 corresponds to the number of light sources 36. Each slider 35 is fixed with a light source 36. By moving the slider 35, the light emitted by each light source 36 can be aligned with the standard hole 41 on the standard template 4.
[0026] Light source 36 can be a laser light source or other light sources.
[0027] The flute support assembly 2 includes a V-groove support 21 and a rotating shaft 22. The rotating shaft is located below the V-groove support 21, and the V-groove support 21 is rotatably connected to the worktable 1 via the rotating shaft 22. With this arrangement, the flute 5 can rotate horizontally within a certain angle range with the V-groove support 21. For example, when drawing lines, the horizontal rotation angle of the flute 5 is usually -10° to +10°.
[0028] The V-groove support 21 can be a V-groove support with a certain strength, such as a wooden V-groove support, a plastic V-groove support, or a metal V-groove support.
[0029] The flute marking device of this utility model, when in use, first determines the appropriate key for the flute based on the length and diameter of the flute tube, and marks the fundamental tone line and tuning line on the flute tube. Find the corresponding standard template on the workbench, then turn on each light source of the adjustable light source assembly. Each light source emits light. First, adjust the angle of the base plate so that the light emitted by each light source illuminates the corresponding standard template. Move each slider on the guide rail so that the light source on the first slider illuminates the first standard hole on the standard template. Lock the position of the slider with the locking bolt, and then adjust the second slider in turn so that the light source on it illuminates the second standard hole. In this way, each hole on the standard template is illuminated by the corresponding light source. After adjustment, adjust the angle of the base plate so that the light emitted from each light source on the base plate illuminates the flute placed on the flute support assembly. Then, rotate the angle of the flute support assembly horizontally so that the light emitted from the light sources corresponding to the fundamental tone hole and tuning hole on the standard template illuminates the fundamental tone line and tuning line on the flute, respectively. The positions on the flute illuminated by other light sources are the positions of the remaining holes on the flute. You can use a drawing pen to draw lines at the corresponding positions to complete the drawing operation on the flute.
[0030] This invention relates to a flute marking device. Before marking, the positions of each light source can be adjusted according to the required standard template fixed on the worktable, resulting in higher positioning accuracy of each light source and thus higher marking precision. This flute marking device has a simple structure, is easy to operate, and can quickly complete the marking operation on the flute. Furthermore, this device can be used for marking flutes of various melodies, demonstrating good applicability.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
